    "abstract": "We show that atomic spin motion can be controlled by circularly polarized\nlight without light absorption in the strong pumping limit. In this limit, the\npumping light, which drives the empty spin state, destroys the Zeeman coherence\neffectively and freezes the coherent transition via the quantum Zeno effect. It\nis verified experimentally that the amount of light absorption decreases\nasymptotically to zero as the incident light intensity is increased.",
